In Java, objects are king. In earlier implementations of the language, there were no primitive data types, and literally everything, including integers, was an object.

I came from the sun

Java is a product of Sun Microsystems, although nowadays it's owned by Oracle.

After drinking me you'll be very active

After drinking java the coffee, you'll be on high alert for a while.

Edit:

and one of the intents of Java (1.2.4 in this document) was that people who used it would have high performance.

You can take me anywhere

As above, since Java is available on so many platforms, including mobile platforms (in fact, it's the primary language used to program for the Android operating system), you can literally take it anywhere you go.

I... honestly can't explain this one. Unless you think Java is a very simple and fair language, in which case my bias from working with it for a year in CS class is going to kick in and say that that last line is patently false.

Edit:

Apparently the answer is that, again, one of the intents of Java (1.2.1 here) was that the language would be simple and familiar, even if in practice it really isn't.

$\begingroup$Is this solved, then? If Joe says that it "executes with 'high performance'", then he's correctly answered "After drinking me you'll be very active"? I get the feeling we're beginning to veer into subjectivity at this point, both in regard to what's an acceptable answer, and in personal opinions on Java.$\endgroup$

Well I already read the answer, so there's no point in explaining my solution, but I think I can explain the line

After drinking me you'll be very active

I think it means:

"to drink sth. in", which means to figuratively absorb something, because you like it so much. For example, if you "drink in" a book then you read the whole thing in one sitting, because you find it that fascinating. And I think it's the same with Java. If you're eagerly learning everything about Java, because you like the language that much, you will be very active in working with it, because you know how to use it.
